Background: The Global Adult Tobacco Survey has 15 key indicators, cigarettes smoked per day (CPD) among daily smokers being one of them. The first wave of GATS in 14 countries indicated that mean CPD use is higher in women than men in India only, which is contrary to the current understanding of tobacco use globally. This study was undertaken to understand the unusual findings for mean CPD use in the GATS-India survey. Materials and Methods: Items B06a and B06b of the GATS India survey questionnaire that collected information on daily consumption of manufactured and rolled cigarettes were analyzed using SPSS software. Exclusive users were identified from these items after excluding the concurrent users of other tobacco products. Cigarette type, exclusive use and gender stratified analyses were made. Consumption of different types of cigarettes among the mixed users of manufactured and rolled cigarettes were correlated. Results: Higher mean number of CPD use among male daily-smokers was observed than their female counterparts in product specific analysis. Mean CPD as per GATS cigarette definition was higher in males than females for exclusive users but a reverse trend was observed in case of non-exclusive users. Use of manufactured cigarettes increased with increase in use of rolled cigarette among the mixed users and around half of these users reported equal CPD frequency for the both types of cigarettes. Conclusions: The anomaly in mean CPD estimate in GATS-India data was due to inclusion of two heterogeneous products to define cigarettes, variation in cigarette product specific user proportions contributing to the average and non-exclusive concurrent use of other tobacco products. The consumption pattern of cigarettes among the mixed users highlights bias in CPD reporting. Definition, analysis and interpretation of 'cigarettes per day' in the GATS India survey need to be improved by redefining cigarettes and making product specific analyses.

Objectives: This systematic review and meta-analysis aimed to assess the association of cigarette smoking with the prevalence of post-endodontic apical periodontitis in humans. Materials and Methods: We searched through PubMed/Medline, Web of Science, and Scopus from inception to December 2020. Risk of bias was performed by using the Newcastle-Ottawa Scale for cross-sectional, cohort, and case-control studies. We performed the statistical analysis in Review Manager 5.3 (RevMan 5.3). Results: 6 studies met the inclusion criteria for qualitative and quantitative synthesis. Statistical analysis of these studies suggests that there were no differences in the prevalence of post endodontic apical periodontitis (AP) when comparing non-smokers vs smoker subjects regarding patients (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.31-1.49; I2 = 58%) and teeth (OR, 1.71; 95% CI, 0.99-2.93; I2 = 72%). Conclusions: Our findings suggest that there was no association between cigarette smoking and post-endodontic apical periodontitis, as we did not find statistical differences in the prevalence of post-endodontic AP when comparing non-smokers vs smoker subjects. Therefore, smoking should not be considered a risk factor associated with endodontic failure.

Cigarette smoking has long been recognized as a major risk factor in the development of coronary heart disease. Several investigators have reported the strong association between smoking and high serum cholesterol, triglyceride concentration, SFA and low HDL cholesterol, PUFA and $\omega$6 concentrations. Therefore, this study was done to investigate the effect of smoking on the serum lipid profile and fatty acid composition of college women. Sixty-one non-smokers and twenty-seven smokers were selected from college women students in the Seoul area. Their lipid intake, serum lipid concentration and fatty acid composition were examined. There were no differences in the general characteristics and anthropometric indices between the smokers and non-smokers. However, alcohol consumption was significantly higher in smokers than non-smokers (p<0.001). The daily caloric intake of smokers and non-smokers were 1875.84 kcal and 1915.53 kacl, respectively. On the other hand, the mean daily intake of lipids and cholesterol were significantly lower in smokers (p<0.05). In smokers, the mean concentrations of serum total cholesterol, LDL-cholesterol and the LDL-C/HDL-C ratio were higher, and the compositions of EPA and DHA were lowe than in non-smokers. There was a negative correlation between the serum triglyceride and PUFA levels in the two groups. Also, serum HDL-C correlated negatively with MUFA in smokers and non-smokers (p<0.01). These results suggest that smoking cause inadequate changes in serum lipid profile and serum fatty acid composition, thereby increasing the tendency for coronary heart disease.

Printing of pictorial health warnings (PHWs) on cigarette packages became obligatory by the Vietnam Law on Prevention and Control of Tobacco Harm in May 2013. Literature from high-income countries suggests that PHWs motivate smokers to quit smoking although their long-term effects have been questioned due to reduction of impact over time. This study aimed to assess the salience of PHWs and smokers' reactions towards PHWs over time. In May 2014 and May 2015, a cross-sectional questionnaire-based household survey was administered to respectively 1,462 and 1,509 Vietnamese male smokers aged 18 to 35. The result showed that salience of the PHWs 2 years after the implementation was higher than at the point of 1 year after the implementation. The proportion of respondents who tried to avoid noting the PHWs was reduced from 35% in wave 1 to 23% in wave 2. However, "Tried to avoid looking/thinking about the PHWs" increased 1.5 times the odds of presenting quit intention compared to those respondents who did not try to avoid looking/thinking about the PHWs (OR=1.5; 95%CI: 1.2-2.0). In conclusion, avoidance regarding PHWs may not work as a barrier when aiming at a higher level of quit intention. Salience of the PHWs may increase in the period shortly after their introduction onto packs but can be expected to decrease with time. In other words, it might be advisable to change or renew PHWs after a period of implementation to maintain their beneficial effects.

This study was carried out to evaluate the relations among workers' general characteristics, work-related behaviors and health related behaviors in a steel industry with 1,134 workers in Pohang. The results were as follows; 1. The mean age of workers was 50 years old and working duration was 15 years and over. Most of them were married(94.5%) and had studied beyond high school (53.0%). They performed three shift work and most of them(63.0%) had experienced industial accidents. The frequency of noise and dust exposure was defined by a minimum of 6 hours per day, and workers complained about noise exposure(62.9%) and dust(55.6%). There were current smokers(67.7%), current drinkers(74.3%) and current exercising workers(32.3%) in the industry. The number of cigarette consumption in current drinkers was significantly high $(13.6{\pm}8.4\;pieces/day)$ and the alcohol consumption in current smokers was significantly high$(104.5{\pm}113.5\;g/wk)$. And the number of cigarette consumption of exercisers was significantly low and the alcohol consumption of exercisers was higher than non-exercisers. 3. The ratio of current smokers on frequent noise in exposed workers versus non-exposed workers was not significantly high but the current drinkers in frequent noise and dust exposed workers was significantly higher than non-exposed. 4. The normal levels of SGOT workers in non-smokers were significantly higher than in current smokers, and the normal levels of LFT (SGOT, SGPT, $\gamma-GTP$ workers in nondrinkers were significantly high. The normal levels of SBP and DBP workers in current smokers were not significantly high but were significantly high in non-drinkers. 5. The ratio of current smokers in voters unsatisfied with their job and working condition was higher than non-smokers, but the ratio of current drinkers in workers satisfied with their job and working condition were higher. 6. The significant factors for SGOT and $\gamma-GTP$ were age, the drinking amount and BMI. But the only significant factor for r-GTP was BMI. The significant factors for DBP were age, the alcohol consumption and BMI. And the significant factors for SBP were age, BMI.

Objectives: To investigate the link between cigarette smoking and muscle strength in Japanese men. Methods: We used data on 4249 Japanese men, aged $43.3{\pm}13.9$ years, in this cross-sectional investigation study. Grip strength and leg strength were measured as indicators of overall muscle strength. Meanwhile, subjects' cigarette smoking habits were recorded by trained medical staff. The effect of cigarette smoking on muscle strength was evaluated. Results: A total of 1618 men (38.1%) were smokers and 1481 men (34.9%) exercised regularly. Significant differences in muscle strength were noted between men with and without a Brinkman index of 400 or greater, after adjusting for age. After adjusting for age, height, body weight and exercise habits, associations between the Brinkman index and leg strength and the ratio of leg strength to body weight were attenuated. Conclusions: Cigarette smoking might be negatively associated with muscle strength, especially grip strength in Japanese men.

This study was done to compare the nutritional status of antioxidant vitamins between college women smokers and nonsmokers. Dietary intakes and serum levels of antioxidant vitamins were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Dietary intakes of vitamin A and C were determined by a quick and convenient dietary intake method. Serum vitamin C level was measured by 2, 4-dinitrophenylhydrazine method and serum levels of vitamin A and E were measured by HPLC. The mean A intake of nonsmokers and smokers was 504.3$\mu$gR.E./day and 450. 4$\mu$gR.E./day and the mean vitamic C intake of nonsmokers and smokers was 51.6mg/day and 50.2mg/day, reapectively. There was no difference in the dietary intakes of antioxidant vitamins between smokers and nonsmokers. The serum vitamin A level, 0.71mg/1 in nonsmokers was not significantly different from that of 0.74mg/1 in smokers. However, the serum vitamin C level, 7.94mg/1 in smokers was 15% lower(p$\ll$0.05) than that of 9.30mg/1 in nonsmokers. The serum vitamin E level, 18.15mg/1 in smoders was also 34% lower(p$\ll$0.05) than that of 27.58mg/1 in nonsmokers. There was no significant correlation between dietary intakes and serum levels of vitamin A and C for both smokers and nonsmokers. These results suggest that cigarette smokers need more dietary intakes of vitamin C and E than do nonsmokers to reach the same serum level.

Purpose: The purpose of the study was to investigate the effects of anxiety, depression and self-esteem on the amount of smoking and nicotine dependency among woman smokers. Method: The convenience sample consisted of 121 unmarried woman smokers. The STAI, the CES-D Scale, the Self-Esteem scale and the FTQ were utilized to measure the level of anxiety, depression, self-esteem, and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Results: Results indicated that woman smokers were depressed. Nicotine dependency was relatively low. Subjects had smoked a mean of 9.58 cigarettes per day. The level of depression influenced on smoking and nicotine dependency. Self-esteem influenced on the amount of smoking and anxiety influenced on nicotine dependency. Conclusion: The results of this study revealed that the amount of smoking of unmarried woman smokers was very high. Both the amount of smoking and nicotine dependency were affected by levels of depression. Education programs and campaigns are needed to prevent smoking of young adult women.

Objectives: The aim of this study was to investigate the relationship between age at cigarette smoking initiation and smoking level among adolescent current smokers. Methods: In 2007, students from one or two classes of the 10th or 11th grade were randomly selected using the probability proportional to size sampling method. In total, 743 current smokers were included. Multiple logistic regression was used to determine the association between age at smoking initiation and smoking level as either frequent, daily, or heavy smokers. Results: The adjusted odds ratios for each smoking level were significantly higher for younger ages of smoking initiation than those for older ages of initiation were (p for trend <0.001). Compared with the students who started smoking in grades 10 to 11, the adjusted odds ratios for frequent, daily, and heavy smokers increased from 2.24 (95% confidence interval [CI], 1.30 to 3.87) to 3.90 (95% CI, 2.02 to 7.56), from 1.56 (95% CI, 0.92 to 2.62) to 3.17 (95% CI, 1.70 to 5.92), and from 2.56 (95% CI, 1.21 to 5.42) to 5.67 (95% CI, 2.61 to 12.30) with younger ages of smoking initiation. Conclusions: Smoking frequency and amount were closely associated with age at smoking initiation. Therefore, smoking prevention programs should be initiated from the young adolescent period.
